Study On Plant Color Construction Of Chengdu Urban Wetland Park

The background of this topic comes from the construction of Chengdu’s ecological belt around the city,and the urban wetland park is the most important part of the urban ecosystem,which has a strong ecological adjustment function and social function,and is also one of the public places where modern people usually have leisure and experience the natural wild interest.As the most common and important landscape element in Urban Wetland Park,plants have relatively important status and research significance.Plant color,as the most intuitive expression form of plants,is also one of the factors that people evaluate the quality of plant landscape,and its construction mode will have an important impact on the urban wetland park landscape.In this paper,the bailuwan Wetland Park in Chengdu is taken as the research object.According to the plant communities in the current wetland park,12 research samples are selected,including 6 plant community patterns and 33 typical wetland plant types.The field investigation is carried out in spring and autumn of the Wetland Park,and the research method of RHS color card comparison record is combined with the online questionnaire survey.After statistical analysis The current pattern of plant color landscape construction and matching in bailuwan Wetland Park of Chengdu City is obtained,and the preference of visitors to the seasonal color of plant community is preliminarily obtained.The main conclusions are as follows:(1)Based on the investigation of Beihu Wetland Park and Jincheng Lake Wetland Park,which are typical urban wetland parks in Chengdu,this paper summarizes the main plant species and plant color,as the case and reference object for the follow-up study of bailuwan Wetland Park.(2)Based on the RHS color card,12 samples of plant communities in Chengdu bailuwan Wetland Park were collected in spring and autumn by means of field investigation and sampling.Through the statistical comparison of plant colors in the two seasons by the way of list,it was concluded that the leaf color and flower color of spring bailuwan Wetland Park tended to be green and yellow,and the brightness and brightness of the overall color were relatively high High,the leaf color and flower color of a few plants tend to be purple,which is used for color embellishment;while in autumn,the seasonal change of plants is obvious,and the flower color or leaf color tends to be yellow and purple.The overall plant color saturation of the park is relatively high,and the color is relatively soft and warm,which gives a clear seasonal hint through the change of plant color.(3)According to the bailuwan Wetland Park in Chengdu,starting from the wetland ecological park around the city of Chengdu,through many field surveys and relevant data analysis,by means of field survey and sampling,and by means of big data questionnaire survey,the author preliminarily obtains the tourists’ seasonal preference for plant color,that is,the autumn plant color is more suitable for tourists’ aesthetic,and based on this,puts forward corresponding sample sites The suggestions on plant color creation at the spot provide some reference suggestions for the following bailuwan Wetland Park to further enrich the plant color.At the same time,it collects the common plant color of Chengdu Wetland Park,and provides some reference for the plant color creation and flora construction of the same type of Urban Wetland Park,and also provides some guidance and reference for the later plant color creation.
